摘要
无线数据传输的重要问题之一是可靠性。基于已有纠错编码的研究成果,通过理论分析,对于选定的[31,16,7]BCH码,分别设计了一种BCH编、译码的快速算法。实际运行结果表明,在给定分组内检/纠3bit差错的条件下,笔者提供的算法可在数据率高达31kbps的信道传输条件下完成实时BCH编/译码计算。
Reliability is a key issue in the field of wireless data t ransmission.Based upon former researches on error-correcting code and indispe nsable t heoretical analysis,31,16,7BCH code is put forward here as an obje ct,and rapid algo-rithms are designed further for BCH c oding and deco ding separately.Practical results show that,in terms of 3bits error correct-ing,algorithms presented in this paper can be applied to real-time BCH coding/decoding computation in the fi elds with data rates up to 31kbps.
